Article abstract of DOI:10.1002/anie.199701351

The perpendicular arrangement of porphyrin units in dimer 1 is reflected in a large excitonic coupling that leads to splitting of the Soret bands and only modest spectral changes in the Q-bands. Compound 1 and the analogous trimer and tetramer are prepared by oxidative coupling of the corresponding 5,15-diaryl-porphyrin and are the first examples of compounds having direct meso,meso-linked porphyrin chromophores, Ar = 3.5-tBu₂C₆H₃.
